The part of the flame closest to the candle or the wood will usually be white, since the temperature is usually greatest near the fuel source. The color blue indicates a temperature even hotter than white. Blue flames usually appear at a temperature between 2,600º F and 3,000º F.

As it relates to hydrocarbon gases, blue flame is indicative of complete combustion whilst a yellow flame indicates incomplete combustion. An LPG blue flame also burns hotter, at around 1,980°C, vs about 1,000°C for a yellow flame.

Which type of fire is hotter, blue or purple? – Quora. As things heat up and combustion becomes more complete, flames turn from red to orange, yellow and blue. And purple color is combination of red & blue color it means that blue fire is more hotter than purple fire.

The color of a fire can change based on what is burning. If you found a chemical or element that burned with a very dark flame (though very likely not ever black), you could have a flame that was quite dark. In this case, the flame would not necessarily be any hotter or cooler than any other.

The hottest fires are from oxyacetylene torches (about 3000 degrees Centigrade) that combine oxygen and gas to create pinpoint blue flames. Color also tells us about the temperature of a candle flame. The inner core of the candle flame is light blue, with a temperature of around 1800 K (1500 °C).

You can make fire burn with a pure white flame. White is an elusive fire color because the fuel that supports a flame burns with its own characteristic spectrum. But, with a little chemistry know-how, you can get white fire. Here’s how to do it, along with tips to make the fire last.

Magnesium sulfate: Makes a white flame.

Green fire is one of the most vibrant forms of colored flames. It’s also one of the easiest to produce with common materials!

Yes. Fire needs heat (high enough temperature), oxygen and fuel. If you take one of the three away the fire will stop. Adding water, the most used technique to extinguish a fire, works this way.

Hold the flame of your “cold fire” right under a water droplet on a stick and see it gradually turn into ice.

If there are no electrons available for bond formation, the substance cannot form a solid. This means that the substance cannot freeze. So, no. It is not possible to freeze fire.

High temperature can provide an optimal environment, but it is not enough to cause a fire unless the quantity of combustible material and oxidizer are within appropriate limits.

To put this into perspective an average house fire will usually burn at a temperature somewhere between 1,000 and 2,000 degrees Fahrenheit though this is pretty variable depending on the combustible materials present in your home.

The only reason a flame can set other things on fire is because of the heat it generates. So the reality is that the only way to catch things on fire (ignoring unusual chemical reactions) is from heat, and other flames just happen to be one way to provide the necessary heat.

The likely explanation for suspected cases of spontaneous human combustion, then, is that there is an external source of ignition—a match, a cigarette, an electrical spark—that sets off the wick effect, but the evidence of it is destroyed by the fire.

Quite often the peripheral bones of the hands and feet will not be burned to such a high intensity as those at the centre of the body, where most fat is located. Body fat acts as a source of fuel and people with more fat will burn at a higher intensity than very thin people.

The human body isn’t especially flammable, she reasons, and has high water content. That’s why it takes flames of around 1600 degrees Fahrenheit over two hours or more to cremate human remains. A cigarette tip, in contrast, only burns at around 700 degrees Celsius.

roughly 3,000 degrees

The most recent death linked to SHC was that of Michael Faherty, 76, who died at his home in Galway, Ireland in December 2010. Dr Ciaran McLoughlin, the coroner tasked with explaining Mr Faherty’s sudden death at his home in Ballybane, made the shock decision of putting it down to SHC.

These include alcoholism, starvation, and diets based on low-carbohydrate and high fat/protein intake. 2. Avoid potentially dangerous sources of flame or high temperature, especially when drowsy. And don’t smoke.

Preventing Spontaneous Combustion

1. Wash and dry items by type and use: Linens, towels, robes, etc.
2. Don’t let soiled or saturated items sit too long: If oily laundry sits in a pile too long the heat generated as the oil oxidizes will increase.

Therefore, when grass clippings are bagged, you have a large amount of clippings in a bag that is generating heat; and if that bag is broke open inside a trash truck or a compost bin, the gases produced by the grass clippings are exposed to oxygen, causing the material to ignite and catch fire (spontaneously combust).

The most common type of Spontaneous Combustion fires are those caused by improperly disposing of oil and stain soaked rags. Spontaneous combustion of oily rags occurs when rag or cloth is slowly heated to its ignition point through oxidation. A substance will begin to release heat as it oxidizes.

No. Baby oil, is another form of mineral oil, and it too has a flashpoint of 335 degrees Fahrenheit which is not technically flammable, but still catches fire quite easily.

Waste disposal methods Oil soaked materials may spontaneously combust and should be properly managed to avoid ignition and heat sources or oxygen rich environments. Collect and store soaked materials in closed, metal containers.

Coconut oil is environment friendly that can reduce the effect of global warming because the combustion of coconut oil produces CO2 that can be used by plant for the process of photosynthesis. Therefore, coconut oil combustion is very intereting to be applied in industries as diesel fuel.

Fish oils are notorious for their self-heating properties. Mineral oils like white spirit, mineral turpentine or lubricating oil are not prone to self-heating and will not cause spontaneous ignition. It is simple to prevent spontaneous ignition since oxygen is needed for it to occur.
